Title: Method for supporting superconductive magnet
Inventor: NAKADA YOICHI
IPC: H01F6/00
Filed: 1989-06-19
Abstract: PURPOSE:To stabilize magnetic field uniformity of a superconductive magnet by a method wherein a support member is housed in a superconductive magnet after load larger than the load which is expected to be applied to the support member is applied to the member. CONSTITUTION:Before a support member 7 is housed in, load larger than the load which is expected to be applied to the support member 7 is applied to it in advance, and then it is housed in a superconductive magnet. When tinsile load is applied to the support member 7 for the first time, displacement varies along with the load as indicated by curve (a) and the displacement returns to point (d) as indicated by curve (b) when the load is removed with plastic deformation of delta resulting. When tensile load is applied for the second time, the displacement is as indicated by the curve (c) and removal of the load is indicated by the curve (b) wherein the curves (c) and (b) are repeated for the third time and thereafter. If the superconductive magnet is housed with plastic deformation of delta applied in advance, the displacement of delta will not occur even if load is applied. Thus since the support member 7 is not deformed even if expected load is applied, an inner vessel 3 does not move thereby stabilizing magnetic field uniformity of the superconducting magnet 1.

Title: Error rate detection circuit
Inventor: SUZUKI HIDEHIKO
IPC: H03M13/00
Filed: 1993-06-25
Abstract: PURPOSE:To accurately detect an error rate even when the error rate gets higher by setting variably a timing pulse interval in an error counter depending on an error check rate. CONSTITUTION:A CRC error detector 1 receiving a data string 11 including a CRC check result generates one pulse on the detection of a CRC error. An output 12 of the detector is counted by an error counter 2. The counter 2 latches a count result of a binary counter 21 by a timing pulse 31 outputted from a timer 3 and clears the count result by the counter 21. Thus, an output D2 from the counter 2 is compared with a value S1 from a threshold level setting circuit 5 at a comparator 4 and when the output D2 is larger than the value S1, an error rate detection output 41 is generated. The timer 3 decreases a count interval of error pulses in response to the increase in the error detection rate. Thus, production of mis-detection is prevented.
